ADJUSTABLE WlNDOW-CORNICE.

SPECIFICATION forming part of Letters Patent No. 223,699, dated January20, 1880.

Application filed July 1, 1879.

To all whom it may concern Be it known that I, WILLIAM W. BoLLEs, ofToledo, in the county of Lucas and State of Ohio, have invented a newand Improved Adjustable Window-Cornice, of which the following is aspecification. I

Figure 1 is a front elevation of the cornice. Fig. 2 is a sectionalelevation on line a; as, Fig. 1. Fig. 3 is a sectional elevation on line:1 y, Fig. 1.

Similar letters of reference indicate corre sponding parts.

The object of this invention is to furnish an ornamental window cornicethat without alteration can be adjusted to a window of any Width. v

The invention consists of an ornamental piece of molding, on which aresecured thicker and grooved or channeled edges, and on each end of whichis rigidly fixed a mortised truss, the whole forming the center-piece ofthe cornice. The side extensions of the cornice consist of two pieces ofmolding that are made to slide in the mortises of the trusses and thechannels or grooves of the edge strips, and meet behind thecenter-piece. The mortises in the trusses conform in their generaloutlines with the outlines of the moldings, and the trusses are also cutthrough from their tops to the nior-tises, in order to make them soelastic that they will not bind on the sliding corniceextensions.

In the drawings, A represents the front piece, which may be of anydesired length, as the length of this determines the range ofadjustability of the cornice.

B B are the grooved edge pieces or top and bottom pieces, that may bemade as ornamental as desired, while the front piece should 0011- formin outline with the side extensions.

0 are the trusses with the vertical cut a in them, that may be drawntogether by the screws 1), and that are provided with the mortises c,that extend through them.

D are the side-extension moldings, that slide in the mortises c and inthe grooves 01 of the top and bottom pieces, and by these are held inplace; or these grooves may be dispensed with and the ends of theextensions be steadied by slotting them and passing thumb-screws throughthe slots and into the back of the front piece.

I am aware that adjustable window-cornioes are not new, nor elasticmortised trusses; and I am also aware that cornioes have been made oftwo like pieces that slide upon each other, to an end of each of whichis secured a mortised bracket or truss whose mortise conforms in itsoutlines with the surface --lines of the.

moldings; but this style of cornice is objectionable in a measure,because the two halves, though parallel with each other, are not in thesame plane, and hence present an irregular appearance. I do nottherefore claim a cornice composed of two like parts sliding upon eachother; but, v

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- The within-described window-cornice,consisting of front piece, A, grooved top and bottom pieces, B B,mortised trusses 0, provided with vertical cut a, and side-extensionmoldings D, constructed and arranged substantially as herein shown anddescribed.

WM. W. BOLLES.
